Thanks everyone for your replies.

I've installed PHP5-FPM alongside HHVM. As the three applications
(wordpress, roundcube and owncloud) will be running on a different
subdomains, I can configure each one individually. So I will use
PHP5-FPM for roundcube and owncloud (as HHVM doesn't work) and stick
with HHVM for wordpress to benefit from its better performance.
Here's the benchmark comparison 'twixt HHVM

Requests per second:    92.40 [#/sec] (mean)

and PHP5-FPM tested on the same page

Requests per second:    35.49 [#/sec] (mean)

Solid
